A random instruction-based fault injection detection method and related apparatus
PendingCN122533734AStrong concealment
The application discloses a fault injection detection method based on random instructions and related devices, and relates to the technical field of information security. In the random instruction generation stage, the application applies a preset mathematical constraint code to one or more encoding bits of the random instruction, and injects the instruction carrying the encoding feature into a downstream operation or memory unit; when the downstream unit executes the instruction, it checks whether the actual calculation result conforms to the preset mathematical constraint code in parallel. If the check fails, it is determined that a fault injection attack has occurred. The application applies a preset encoding constraint to the random instruction, so that the random instruction itself carries verifiable fault detection information; the downstream module uses the encoding feature to perform fault injection detection in parallel, so that the random instruction has both side channel defense and fault injection detection functions. The detection logic is deeply integrated with normal instruction flow, has strong concealment, and is difficult to be evaded by attackers.
